ORE-CONCENTRATOR.

LQWLTB.

To all whom it may concern:

Be it known that we, (1) HANNIBAL Sco- VELL and (2) LESLIE E. SCOVELL, citizens of the United States, residing at (1) Galena and (2) Columbus, in the county of Cherokee and State of Kansas, have invented certain new and useful Improvements in Ore- Concentrators; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in ore concentrators.

The object of the present invention is to improve the construction of ore concentra tors more particularly that class of devices wherein the ore is graded and concentrated and to provide a simple, practical and efficient ore concentrator of comparatively inexpensive construction equipped with means for reciprocating a screen both vertically and longitudinally in a tank and capable of adjustmentjto secure the desired position of the screen in such elliptical orbit produced by the said vertical and longitudinal reciprocatory movement.

A further object of the invention is to provide actuating mechanism of this character adapted for use in various types of ore separators and similar devices where a reciprocatory-j or vibratory motion of this character is desired, and to enable the separating means to deliver the separated and concentrated ore into a pocket for enabling the ore to be conveniently removed.

With these and other objects in view the invention consists in the construction and. novel combination and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing Figure 1 is a plan view of an ore concentrator constructed in accordance with this invention, Fig. 2 is a side elevation of the same, Fig. 3 is a central longitudinal sectional view of the ore concentrator, Fi 4 is a transverse sectional *fi iew taken su stantially on the line 44= of a .1: numerals 'of reference desiate cor- Patented Dec. f2, T916.

responding parts in the several figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the ore concentrator comprises in its construction, a suitable tank or box 1 for holding water .or other fluid for washing the ore. The tank is designed to be properly supported in any suitable manner preferably by legs 2 and 3 and it is provided at one end with a depending extension 4 forming a pocket for the reception of the graded and concentrated ore and provided at the bottom with a suitable discharge gate 5. Journaled in suitable bearings 6 at the upper edges of the sides of the tank at points intermediate of the ends of the same is a transverse shaft 7 having keyed or otherwise secured to it at one end thereof, a driving pulley, 8, which is designed to be connected by a belt with .any suitable source of power but any other suitable means may of course be employed, for actuating the ore concentrator. The transverse shaft is provided with inner and outer eccentrics 9 and 10 arranged in pairs and located respectively between the sides of the tank and exteriorly thereof as clearly illustrated in Fig. 1 of'the drawings. These eccentrics which are adapted to impart vertical and longitudinal vibratory or reciprocatory movement to a carrier frame 11 are adjustably secured to the transverse shaft in any desired manner for varying the elliptical movement imparted to the carrier frame by the said vertical and longitudinal movement. The adjustment of the eccentrics will enable the major axis of the ellipse described by the carrier frame to be arranged either in a horizontal or inclined position to secure the desired progressive movement of the material longitudinally of a'screen 12 carried by the said frame 11. The screen 12 which is preferably removable is supported upon horizontal or longitudinal cleats 13 mounted on the inner faces of the sides of the carrier frame and located a slight distance below the surface of the liquid within the tank. The carrier frame is of oblong form being composed of spaced sides, and transverse connecting bars or members but it may be of any desired construction as will be readily understood.

The carrier frame is equipped at its ends with transversely disposed hanger rods 14:

provided at their outer ends with anti-fric said pocket on by the outer eccentrics 10 of the transverse shaft whereby the side leversare oscillated to ralse and lower their outer arms whlch support the carrier frame.

By this construction the carrier frame is reciprocated or vibrated vertically. The carrier frame is also provided at a point intermediate of its ends with a transverse rod 19 which is connected by pitnien 20 with the inner eccentrics 9, the said pitmen 20 having suitable straps 21 to embrace the eccentrics which vibrate or reciprocate the carrier frame longitudinally of the ore concentrator, the anti-friction devices of the hanger rod permitting the latter to move longitudinally of the outer arms of the side levers so that the carrier frame pal-takes of the resultant ofthe upward and downward and longitudinal movement. The hanger rods at the end portions of the carrier frame and the transverse rods 19 at the intermediate portion of the carrier frame may be secured to the latter in any preferred manner. The tank is provided at one end with a feed trough or chute 22 of any desired construction and in the operation of the ore concentrator the screen is carried upwardly and downwardly and longitudinally of the tank through the water in an elliptlcal path and the material is caused to move progressively longitudinally along the screen over the surface thereof, the rapidity of such progressive movement being controlled by the adjustment of the eccentrics to secure the desired action of the ore concentrator on the material before the waste is in the forward movement automatically ejected at the overflow end of the tank. This will permit the fine Values to pass through the screen and collect upon the bottom of the tank. The concentrated and separated material lying upon the bottom of the tank is carried to the pocket 4 by transverse rods or bars 23 secured to the bottom of the carrier frame which in its elliptical path of movement is carried upwardly and forwardly and downwardly and rearwardly so that the transverse bars or rods will operate to move the values along the bottom ofthe-tank to the 4 where they may be continually drawn off through the discharge gate 5.

By using a tank or receptacle without a bottom, various substances may be cleaned and separated and classified in a dry condition. By means of the same arrangement of the actuating device and carrier frame, provided with a suitable bench or frame for its the tank and support, any rippled tabletop or deck ordinarily used for the concentration of ore values properly adjusted on top of the carrier frame, will be given a perfect movement for the separation and classification of ore values, each according to its specific gravity and classification. The device is especially adapted to this class of ore concentration.

What is claimed is 1. A device of the class described including an approximately horizontally disposed movable frame having a screen, longitudinally disposed side levers arranged in an approximately horizontal position and forming side rails, said frame being supported upon and slidable along the side levers, means for moving the frame longitudinally of the levers and means for oscillating the levers to raise and lower the frame.

2. A device of the class described including' a tank provided at one end with a depending pocket or extension and adapted to contain a liquid, a carrier frame having spaced sides extending into the tank, said carrier frame being also provided with transverse bars or rods located at the lower edges of the sides adjacent to the bottom of the tank, a screen also carried by the said frame and means for reciprocatin the frame both vertically and longitudlnally whereby the material on the screen will be separated and the material collected on the bottom of the tank will be moved toward the pocket by the said transverse bars or rods.

3. A device of the class described including a support, side levers fulcrumed intermediate of their ends at opposite sides of the support and having inner and outer arms, a carrier frame slidably supported by the outer arms of the said levers, a transverse shaft provided with eccentrics arranged to vibrate the inner arms of the levers to reciprocate the carrier frame vertically and means connected to the shaft for recliprocating the carrier frame longitudina ly.
